- Centrifugal air blower 304 is shown coupled beneath air cushion cargo shuttle 114.
- Air cushion cargo shuttle 114 may comprise one or more centrifugal air blowers.
- Centrifugal air blower 304 is controlled by centrifugal air blower controller 302.
- Air cushion cargo shuttle 114 may comprise one or more centrifugal air blower controllers.
- each centrifugal air blower has one associated centrifugal air blower controller, though in various embodiments one centrifugal air blower controller controls multiple centrifugal air blowers.
- Centrifugal air blower controller 302 may provide power and instructions to centrifugal air blower 304 to control how and when centrifugal air blower 304 operates.
- Centrifugal air blower 304 comprises inlets 404. Inlets 404 allow the centrifugal air blower 304 to receive air from outside volume 402 and deliver that air to volume 402.
- each centrifugal air blower has one associated inlet, though in various embodiments one centrifugal air blower is associated with multiple inlets. In further embodiments, a single inlet may supply air to one or more centrifugal air blowers.
- Volume 402 of air cushion cargo shuttle 114 is shown in fluid communication with an outlet of centrifugal air blower 304.
- centrifugal air blower 304 may blow air beneath air cushion cargo shuttle 114 and, more specifically, into volume 402. Volume 402 is shown in proximity to floor panel 112.
- air cushion cargo shuttle 114 has four centrifugal air blower controllers 302, 414, 416, and 418 driving four centrifugal air blowers 304, 420, 422, and 424 to blow air into four different volumes 402, 426, 428, and 430.
- Each centrifugal air blower controller may further comprise a proximity sensor that may be configured to measure the proximity of a portion of air cushion cargo shuttle 114 to floor panel 112.
- proximity sensors 406, 408, 410 and 412 may be associated with each centrifugal air blower controller 302, 414, 416, and 418.
- Proximity sensors 406, 408, 410 and 412 may be used in a closed loop control mechanism to modulate the output of four centrifugal air blowers 304, 420, 422, and 424.
- centrifugal air blower controllers 302, 414, 416, and 418 may command four centrifugal air blowers 304, 420, 422 to blow air into volumes 402, 426, 428, and 430 until the proximity sensors 406, 408, 410 and 412 indicate that a desired proximity has been reached.
- data from proximity sensors 406, 408, 410 and 412 may be used to detect and compensate for uneven cargo loads. For example, in the event cargo 202 shifts to one portion of air cushion cargo shuttle 114 or otherwise exerts more force on a portion of air cushion cargo shuttle 114 relative to another, data from proximity sensors 406, 408, 410 and 412 may detect that one portion of air cushion cargo shuttle 114 is not as far from floor panel 112 as one or more other portions of air cushion cargo shuttle 114. In that regard, where insufficient distance from floor panel 112 is achieved, a centrifugal air blower controller may command its associated centrifugal air blower to increase output to compensate for the uneven load.
- cargo such as cargo 202 may be loaded onto air cushion cargo shuttle 114 at an aft position, such as a position proximate aft shuttle drive unit 102.
- Cargo 202 may be positioned onto air cushion cargo shuttle 114 using power drive unit 308 and roller 306.
- air cushion cargo shuttle 114 may be in contact with floor panel 112.
- a control system for centrifugal air blower controller 302 may instruct centrifugal air blower 304 to begin operation.
- air from inlets 404 is pulled into centrifugal air blower 304 and centrifugal air blower 304 blows this air into volume 402.
- the increased air pressure may act to lift air cushion cargo shuttle 114 apart from floor panel 112.
- the phrase "lift apart” may refer to movement of air cushion cargo shuttle 114 in the positive z direction.
- the pressure in volume 402 may reach between 1 psi (6.89 kPa) to 10 psi (68.9 kPa), between 2 psi (13.7 kPa) and 6 psi (41.3 kPa), and about 4 ps (27.5 kPa), where the term about in this context may refer to +/- 0.5 psi (3.4 kPa).
- a control system comprising, for example, a processor and a tangible, non-transitory memory may be configured to be in electrical and/or logical communication with centrifugal air blower controller 302.
- the control system may communicate with centrifugal air blower controller 302 via one or more shuttle belts.
- the control system may instruct the centrifugal air blower controller 302 to start, stop, and modulate the output of centrifugal air blower 304.
- centrifugal air blower 304 cargo 202 may lift apart from floor panel 112, thus reducing the friction between air cushion cargo shuttle 114 and the floor panel 112. Stated another way, dry friction may be equal to the coefficient of friction multiplied by the normal force. By eliminating the contact between air cushion cargo shuttle 114 and the floor panel 112, the two surfaces do not interact to cause friction. In various embodiments, there may be contact between air cushion cargo shuttle 114 and the floor panel 112 during operation of centrifugal air blower 304, though the air pressure will oppose the normal force (i.e., force in the negative z direction) exerted by cargo 202 and thus friction will be reduced because of this reduction in the normal force.
- the normal force i.e., force in the negative z direction
- the forward shuttle drive unit 204 may rotate its bobbin, causing forward drive shuttle belt 208 to pull air cushion cargo shuttle 114 and cargo 202 forward.
- Air cushion cargo shuttle 114 may pass over tie points 122 in a stowed configuration.
- Aft shuttle drive unit 104 may be allowed to exert a low level drag force on aft drive shuttle belt 108, thus allowing aft drive shuttle belt 108 to extend in a forward direction.
- a low level drag force exerted by aft shuttle drive unit 104 may prevent excessive cargo velocity and may maintain stability in the event an aircraft is not precisely level.
- the control system may instruct the centrifugal air blower controller 302 to turn off or lower the output of centrifugal air blower 304.
- air cushion cargo shuttle 114 may move in a negative z direction and contact floor panel 112.
- cargo 202 may come to rest on support rails 222.
- the air cushion cargo shuttle 114 may separate from the cargo 202 as the cargo 202 is restrained from motion in the negative z direction by support rails 222.
- air cushion cargo shuttle 114 may be brought aft to load additional cargo.
- the aft shuttle drive unit 102 may rotate its bobbin, causing aft drive shuttle belt 108 to pull air cushion cargo shuttle 114 aft. Additional cargo may now be loaded and the process may proceed again.
